I've just scourged my way through culture shock and found it rather amusing, great work Telltale! The story and characters were dead on par. I thought the voices of the characters were great too, unlike some of the other neocons on this forum. The only gripe I have is with the difficulty, some parts were overly obvious. The antenna for example needed for the helmet. One of the great things of hit the road was the outragious solutions to each puzzle. The solutions in culture shock were more logical and less "lunatic" I found.
All in all though I think it’s a great success. If the caliber continues I'll be throwing wads of cash your way.
p.s Any word on a re-release of the sketchbook? I wouldn't mind getting my grubby hands on one.
